CFD STUDY OF THE AIR FLOW AND HEAT TRANSFER IN A LOUVERED FINNED HEAT EXCHANGER FOR VEHICLES

The air flow and the heat transfer in louver fins were simulated using the CFD method. The results of the CFD calculations on the air pressure drop in the air flow and on its outlet temperature were compared with the experimental data, obtained for the air velocities 1.5, 2.5, 3.5, and 4.5 m/s. In all these cases, the errors in determining the pressure drop in the air flow and in its outlet temperature were within 10%. The influence of the louver angle, the fin pitch, and the louver pitch on the rate of heat transfer in the air flow and on the pressure drop in it were investigated
